Frequency Analysis and Measurement of the Electrocadiogram in the Athletic and Emotional Loads

An electrocardiogram shows an active potential of heart as a function of time and is very important information on a living body. The present paper reports the result of the electrocardiogram and its frequency analysis which were measured in an athletic and an emotional loads for students. Students were tested a riding a bicycle as the athletic load and a paing TV game as the emotional load. A heart rate in the athletic load shows about twic and an amplitude of P-wave and T-wave in the electrocardiogram becomes higher than that in a complete rest condition. In the frequency analysis of electrocardiogram, each frequency component which coresponds to P-wave, T-wave, awidth of QRS and a width of RR shifts to the higher frequency in the athletic load. And, the amplitude for each frequency component decreases with frequency, f, as a function of (1/f) in the athletic load. In the emotional load, the heart rate rises 20% up in comparison with it in the complete rest condition. The present paper discusses on the relation between the frequency analysis and each load
